ANTISLIP ATTACHMENT FOR LOOMS.

Application filed April 5. 1921.

To all 1.0710722. it may con cern Be it known that I. \VILLIAM SnrMoNs, a citizen of the United State... residing at New York city. in the county of New York and State of New York. have invented new and useful. Improvements in Antislip .At-. taclnncnts for Looms. of which theflollowinn; is a specification.

This invention relates to anti-slip attachmcnts for looms and in particular to looms used in the weaving of ribbons.

One of the principal objects of the inven 'tion is to provide a device whereby the rib bon after being woven and fed from the loom will not be permitted to make retrograde movements. 2

Another object is to provide a device of this nature which shall be oi. simple character, consisting of? -few parts and readily attached to any existing loom of the nature indicated.

Another object is to provide a device of this nature in which the gripping member may be released from the ribbon and automatically hold in released position at the will of the operator.

With these and other objects in view which will be more apparent as the specification proceeds, the invention resides in certain novel features of construction and combination and arrangement of parts, the essential features of which are hereinafter fully described are particularly pointed out in the appended claims and are illustrated.

in the accompanying drawing in which Figure 1 is a vertical section of a portion of a loom provided with my improved antislip attachment.

Figure 2 is a perspective view of the attachment per se.

Figure 3 is a detail view of the gripping roller per se.

Like characters oi reference refer to like parts in all views.

In looms as at present constructed and particularly in ribbon looms. the ribbon after being woven is usually ted downwardly by means of a roll having roughened surface usually of sand paper. In the course of time, operation of the loom causes the roll to wear more or less smooth and in such cases when an upward tension is placed on the woven ribbon. the ribbon is drawn back. The present device contemplates a Specification of Letters Patent.

simple means for preventing such rctrograde movements of the woven ribbon.

Referring more particularly 'to the dra ing. 10 represents what is known as the front glass bar of the loom and 11 represents the breast piece thereof. As the ribbon is woven it is fed over the bar 10 and down in proximity to the breast piece 11.

My attachment consists of a piece of sheet metal 12 which is bent at right angles at 13 and provided in one leg with a slot 14 through which a screw or boltpasses into the lower surface of the breast piece so as to secure the device thereto. The vertical portion of the member 12 has large cars 16 bent up at opposite sides and in these cars are formed slots 17 havingofiset lower legs 18. A roller 19 is provided with ridges or corrugations on its surface and is mounted between the ears 16 by trunnion screws 20 passing through the slots 17 and into the roller 19. Springs 21 are secured to the screws 20 and. have their opposite ends seated. in the member 12 near the top thereof. These springs tend constantly to force the roller 19 upwardly into contact with the ribbon which is being fed down by the heretofore mentioned friction means (not shown). As the ribbon passes down, the roller offers little or no resistance to such movement; but the moment tension is placed on the upper portion of the ribbon so to cause it to feed back. the roller 19 jambs the ribbon between itself and the vertical face of member 12 thereby preventing such upward movement.

At times the weaver ties knots in the rib bon above the bar 10, and the slot 17 is inclined so that the roller 19 may move far enough away from the vertical taco ot' the member 12 to permitknots to pass freely downwardly. At other times the weaver may desire to move the ribbon upwardly and in this case he moves roller 19 downwardly until the trunnion pins 20 are seated. in the horizontal legs 18 of the slots, the roller being maintained in this inoperative position until again released therefrom by the operator.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my invention, and I there- .fore do not limit myself to the exact details of construction herewith set forth nor to anything less than the whole of my invention limited only by the appended claims.

What is claimed as new is 1. An anti-slip attachment for looms eomprising a body member, having a right angle bend, orient the legs of said member being formed for adjustable attachment to the breast piece of a loom apair of ears extending at right angles to the other leg of said body member and defining a ribbon passage Way and means supported by said ears for permitting free movement of a ribbon through said passa e way in one direction antl for antomatical y preventingmovement of said ribbon in the opposite direction.

2. In a devised the class described, the combination of a body member,formed with a horizontal attaching portion, a vertical portion having ears bent up at the sides In testimony whereof I have ailixed my signatm'e.
